Question

The speeds of P and Q are in the ratio 5:4. P
takes 20 minutes less than Q to reach the
destination. In what time does P reach the
destination?

Answer 1

Answer:

P reaches the destination in 1h 20 min. Please mark me as brainliest.

Step-by-step explanation:

Let the speed of P be 5x and speed of Q be 4x. (As ratio of the speeds is 5:4)

Let the distance be d.

Time taken by P = d/5x

Time taken by Q = d/4x (As t = d/s)

d/4x - d/5x = 20 min (Given)

(5d - 4d)/20x = 20 min

d/20x = 20min

d/20x * 4 = 20 min * 4

d/5x = Time taken by P = 80min

= 1h 20 min
